97 tbird coolant crossover?

Hi all. Question about the 97 tbirds. The radiator fluid has been getting low a lot faster than it used to so I've been thinking I will need to do the NPI to PI swap soon. Was looking at it today for the leaks and found it leaking around the end of the crossover.

What I noticed and what I don't get is that it already has a aluminum coolant crossover on it? Did the 97 tbirds come that way from the factory? Or was it most likely done due to a recall or TSB?

Can I just pull off the crossover, install new gaskets on both ends then reinstall?

Not interested in doing the NPI to PI for for 15 hp. Its a go to work, get the groceries car and has plenty of power for those duties.

I bought the car in 2009 for $3200 with 95,000 miles. It has 205,000 miles on it now and starts right up and runs great with the original motor, tranny and rear end.. Some times I think the motor is going outlast the rest of the car..IMO Ford made a good one when they designed and made the 4.6l.

If it's leaking at the crossover seal; I've never seen those seals for sale, but it doesn't mean they don't exist.
You likely need an intake.

If the intake gasket is leaking, which is more likely, you need a new gasket.

I wouldn't buy a NPI intake if I needed a new intake.

Pull it apart, and see if it's the intake or the gasket under it.

PI intakes are cheaper and easier to find than aluminum crossover NPIs these days, that's not exactly a wild choice for a DD. The issue you're having, if it's leaking between the crossover, is likely the plastic part of the intake holding in the gaskets is cracked and failing, and like grog said there's no source for new ones even if they were the sole issue. A bead of RTV will probably suffice though.

Avoid parts store aftermarket intakes like the plague though, the quality is subpar and the plastics don't hold up as well as OEM

Agree 100%.

But not on the plastic intake decision. We can blame that on the auto industry as a whole, since most switched to plastic around that time. Cost savings and weight savings, but the consumer pays for it eventually.

If you're not car savvy, it can go undetected for a while and you end up with a major problem and costly repair. Especially if the car overheats.

Found a video where a guy had one off and he said it has orings between the crossover and IM.

I'm going to have to take the IM off anyway because the crossover is held on by 3 screws on each side on the botom of the manifold and I don't think I can access them all with the IM still on.

Thanks, but I think I'm going to see if I can fix what I have for now. If I can't will send a pm.

Based on your pic's I believe you have the same aftermarket intake I have on my '97 Cougar: Dorman #615-178. The giveaway is the two ears of the black bracket above your alternator. I cut those ears off when doing my install.

The Dorman product does have the 'O' ring style flexible rubber gaskets in the intake. When installing my intake I added RTV around those gaskets (someone on line recommended this) and haven't had a leak yet. I did the job about 45,000 miles (3 years) ago.

The Dorman product has larger runners than the stock engine. I noticed an improvement in HP using my seat-of-the-pants dyno.

If you redo the intake you will notice the shape of your openings on the intake are not very well matched to the heads.

The Dorman webpage says something about integrated gaskets and "Designed Specifically to Work w/Dorman OE Solutions Intake Manifold Gaskets Only". https://www.dormanproducts.com/p-30036-615-178.aspx

The dorman intake loses a lot over stock.

I'd still go PI.

Just curious if you ever actually saw where the leak was from. I have seen a lot of the earlier 4.6 leak at the heater pipe under the intake.
keep us posted.

This is true; I forgot the OG intake has a short piece of tubing, maybe 2" long in the valley.

Eliminating that is one of the advantages of the PI swap.

And avoiding the corrosion marks on the heads, where the original gaskets were.

The Dorman website seems to have conflicting information:

This quote is from the instructions:
"This updated manifold does not require additional intake gaskets. The intake gaskets are already
installed into the manifold."

https://static.dormanproducts.com/do...615-178_IS.PDF

All I can say is the Dorman one I installed (part number 615-178) with that part number had the integrated gaskets in the intake. I think they had a running change to integrate the gaskets.

I have a Dorman intake with an AL cross over if you want it. Ill have to double check itll be worth it for you to use but it served me well for the 2500 miles I put on it. If its good then $20, you pay shipping, and its yours.

First: Stacie, 1996 Tbird LX, mild build NPI engine, PI cams and intake, Long tube headers, Jmod.

Second: Ellie, 1989 Tbird SC, r̶e̶s̶t̶o̶r̶i̶n̶g̶ ̶t̶o̶ ̶b̶e̶ ̶n̶e̶w̶ ̶d̶a̶i̶l̶y̶. off the deep end

Third: 1997 Dodge Ram 1500, thirsty daily.

Fourth: 1990 Tbird SC, GT40 5.0 mated to m5r2, BBK long tubes, motor out the hood, drift car.
